Kourtney Kardashian and Scott Disick's third child, Reign Aston, entered the world on Dec. 14, which was coincidentally also his big brother, Mason's fifth birthday. Proud mama Kourtney took to Instagram this Sunday to share this sweet snap of baby Reign, along with the caption, "Madly in love with my little Reign Aston Disick."
While baby Reign's debut was a low-key one, for a long time running, it seemed People had a monopoly on introductory celebrity baby photos. Nicole Richie, Christina Aguilera, Jennifer Lopez, and the Jolie-Pitts all turned to the well-established magazine to show off their newest family members. However, today, many celebs are turning to competitors who are doling out generous offerings to new parents. Others are releasing their own photos — either on their own or through photo agencies — to bypass the whole magazine scenario. See how your favorite Tinseltown parents debuted their little ones, and tell us how you think the newest Hollywood babies will be introduced to us!
